I have know help, but just wanted to say that you're not alone. I'm having the same problem right now. My wife is being awesome and fabulous and supportive and downright happy for me....And I keep waiting for the other shoe to drop.
So in search of love and laughter, I'll be travelling 'cross this land,
Never sure of where I'm going, for I haven't any plan.
And in time when you are ready, come and join me, take my hand
And together we'll share life out on the loose.
